I'm not sure what the modern standards are, but if you are writing in C, pre-allocate as much as possible. Any kind of garbage collection is just extra processing time and ideally you don't want to run out of memory during an allocation mid-execution.

People may frown at C, but nothing beats getting your inner loops into CPU cache. If you can avoid extra fetches into RAM, you can really crank some processing power. Example projects have included computer vision, servers a custom neural network - all of which had no business being so fast.
